Numerical simulation for a practical large-size pellet implosion

In this paper we introduce and discuss a concept of a large-size-pellet inertial confinement fusion(ICF) in which a fuel pellet contains the deuterium-tritium fuel of about one gram. In the large-size-pellet ICF the fuel compression ratio is about 100 times of the solid density in order to realize ρR >3g/cm². Because of the low compression ratio, the constraints required for the fuel compression are relaxed compared with those for the high-compression implosion scheme of a small pellet. This concept of the large-size-pellet implosion may present an alternative way to the ICF. In this paper we present the one-dimensional numerical analyses for the large-size-pellet implosion in the impact ICF. The simulation results show that an enough fusion energy output may be obtained in the large-size-pelletICF.
